CLEANSING-MATERIAL INJECTOR FOR STEAM-BOILERS.

SPECIFICATION forming part of Letters Patent No. 506,045, dated October3, 1893.

Application filed May 15 1893. Serial No. 474,213. (No model.)

To all whom it may concern.-

Be it known that We, EUGENE JONES and DANIEL W. COLLINS, of LittleFalls, in the county of Herkimer, in the State of New York, haveinvented new and useful Improvements in Cleansing-Material Injectors forSteam- Boilers, of which the following, taken in connection with theaccompanying drawing, is a full, clear, and exact description.

This invention relates to the class of appliances which are employed forintroducing cleansing material into steam-boilers While in operation. 1

Our present invention is specially designed to introduce the cleansingmaterial into the boiler through the feed-water pipe. And it consists inthe improved combination with; the boiler and feed pipe, of the pipeswhich conduct the cleansing material and steam to that portion of thefeed-pipe which is contained between the check-valve and stopcock. Thispermits steam to be introduced into said portion of the feed-pipe toheatlthe same preparatory to introducing therein the cleansing material,all of said pipes being provided with suitablevvalves by which'tocontrol the operation of the apparatus, all as hereinafter more fullydescribed and specifically set forth in the claim.

The annexed drawing presents a side elevation of an apparatus embodyingour invention.

B represents the boiler and P- the feed water-pipe which is providedwith the ,check-valve A and stop-cock D. Be-

tween said check-valve and stop-cock is the pipe a' attached to the topthereof and rising therefrom and provided with the valve a'. To the topof this pipe -a is attached the chamber G- from the top of which extendsvertically the pipe b which is provided with the valve b'- and hassecured to its upper end the funnel b.

Between the valve b and chamber0 the pipe bhas attached to it the pipe cwhich is extended to the dome or steam-space of the boiler and isprovided with the valve c.

Directly opposite the pipe cis the pipe -c l attached to the pipe -b andextended to and communicating with the feed waterpipe P at a pointbetween the check-valve A and stop-cock D. Said pipe dis provided with avalve d'.

Directly under the pip e a and preferably in line therewith js thedischarge valve -e connected to the' feed-pipe P.

The operation vof the described apparatus is as follows: To introducethe cleansing material into the bo'lergthe stop-cock -D and valves c' and' are to be closed, and the valves e and a' to be opened to allow theWa /er to escape from the pipes ct\and b,, chamber -C and the portion ofthe feed-pipe between the stop-cock and oh ck-v lve. \Then the valves eand a" ,rettdlbe closed and the valves c and be opened to admitsufficient steam to cute the chamber C and feedpipe Pt'o arm the same.Then the latter valves are t be closed and the valve -b openedgand thecleansing material to be introduced into the funnel b"- from whence itpasses to the chamber O. Then the valve b'- is to be closed, and thevalves c' and a'- to be opened to force the cleansing material from t echamber O into the feed-pipe P- by he pressure of steam admitted throughthe pipe c. Then the valves c' and a'- are to be closed and thestop-cock D opened to allow the feed water to carry the cleansingmaterial into the boiler. The feed water and cleansing material becomingpartly heated between the stopcock and check-valve allows said cleansingmaterial to more readily circulate with the water in the boiler.

What we claim as our invention is The combination, with the boiler, feedwater pipe P and stop-cock and check-valve attached to said pipe, thepipe arising from the pipe -P- between the stop-cock and check-valve andprovided with the valve a, the chamber -G mounted on the pipe a-, thepipe b extending vertically from the top of said chamber and providedwith the valve b and funnel b' the pipe c connected to the pipe bbeneaththe valve thereof and extending to der the pipe a substantially asdescribed and communicating with the steam-space of and shown. theboiler and provided with the valve c, In testimony whereof We havehereunto the pipe d connected to the pipe b signed our names this 8thday of May, 1893. 5 directly opposite the attachment of the pipe 4EUGENE JONES.
